Hauensuoli (Pike’s gut in English) is a narrow strait between two skerries off the coast of Tulliniemi. Known as the “Guestbook of the Archipelago”, it is a unique attraction featuring 339 names and coats of arms carved into the rock. These carvings tell the story of journeys made by nobles, soldiers, and merchants dating back to the 15th century.
In recent years, the rock carvings have been cleaned and restored by the association Hangon museon ystävät ry, making them easier to see once again.
In addition, a guide to the carvings has been created and can be found here
Gustavsvärn is the best kept part of a four-part fortress on an islet outside of Hanko. The fortress was built by the Swedes in the late 18th century, who added a lighthouse in 1951. The attendant’s house is well kept and maintainted by the Finnish Lighthouse Society, who sell souvenirs there in the summer.
